1. Firstly, you need to create both number series.
2. Secondly, you need to define the first number series in setup (as per our example, that would be in Sales & Receivables Setup, Numbering tab, “Invoice Nos” field, select “CSI” No. Series).

4. In the opened form, define second number series (as per our example, that would be FSI):

And that’s it! Now, when creating sales invoices, all you need to do (after clicking F3, or Edit > New), is to drill down into “No.” field:

And you will be able to select one of the two number series: CSI or FSI:
